Beneficial bacteria grows all over the gravel in forms of colonies (same way it does in your biomedia in your "top box"). Gravel has an almost immediate impact on water clarity, and then it goes to work on water quality because the tiny microbes eat at the tiny particles that are in your water. The more space you allow beneficial bacteria to colonize, the better chance your pond has at staying in balance.
We often hear people exclaim that when they tried adding gravel it was too hard to clean and it got mucky looking. Cleaning it in the spring with a pressure washer makes the job easier and during summer, remember: dirty rocks means it is doing its job. If a filter did not get dirty, then it is not filtering right? Yes, gravel will get dirty, so maintain it, clean it and let it continue to do its job. If you don’t clear your gravel, it will get so jammed packed and cluttered with debris. If you really neglect it you will cause your water quality to suffer.
